Maternitatis Beatae Mariae Virginis / Maternity of the Blessed Virgin Mary: "the Jerusalem above is freeborn, and she is our mother"

Therefore, brothers and sisters, we are children not of the slave woman but of the freeborn woman. For freedom Christ set us free; so stand firm and do not submit again to the yoke of slavery.

-- Gal 4:22-24, 26-27, 31–5:1

Holy Mary, Mother of God: With Elizabeth we marvel, "And why is this granted me, that the mother of my Lord should come to me?" Because she gives us Jesus, her son, Mary is Mother of God and our mother; we can entrust all our cares and petitions to her: she prays for us as she prayed for herself: "Let it be to me according to your word." By entrusting ourselves to her prayer, we abandon ourselves to the will of God together with her: "Thy will be done."Pray for us sinners, now and at the hour of our death: By asking Mary to pray for us, we acknowledge ourselves to be poor sinners and we address ourselves to the "Mother of Mercy," the All-Holy One. We give ourselves over to her now, in the Today of our lives. And our trust broadens further, already at the present moment, to surrender "the hour of our death" wholly to her care. May she be there as she was at her son's death on the cross. May she welcome us as our mother at the hour of our passing to lead us to her son, Jesus, in paradise.

-- CCC 2677

At once virgin and mother, Mary is the symbol and the most perfect realization of the Church: "the Church indeed. . . by receiving the word of God in faith becomes herself a mother. By preaching and Baptism she brings forth sons, who are conceived by the Holy Spirit and born of God, to a new and immortal life. She herself is a virgin, who keeps in its entirety and purity the faith she pledged to her spouse."

-- CCC 507
